  • FIGURE 1 is a perspective view of a distributed load version of the locked multiple pile foundation.
  • Figure 1 includes top plate 100, locking component 102, piles 104, elliptical holes 106, tightening nut 108, round hole 110, tightening bolt 112, pile cap 114, and round hole 116.
  • Piles 104 are directed through elliptical holes 106 on top plate 100.
  • Top plate 100 and locking component 102 are connected by tightening bolt 112, which passes through round holes 110 and 116 and is secured by tightening nut 108.
  • As tightening nut 108 is tightened the distance between top plate 100 and locking component 102 is reduced until locking component 102 engages piles 104, forcing piles 104 to bind and lock in elliptical holes 106.
  • Pile caps 116 are provided to prevent contaminants from entering the otherwise exposed open end of the driven pipe piles 104.
  • FIGURE 2 is a top view of the top plate of FIGURE 1 with elliptical holes for receiving piles, and round holes for receiving tightening bolts, with a hole configuration A and a hole configuration B .
  • FIGURE 3 is a top view of a top plate for a concentrated load version of the foundation, with a hole configuration A and a hole configuration B.
  • FIGURE 4 is a side view of concentrated load foundations using the top plate B from
  • FIGURE 3 with a locking type A, B, and C.
  • FIGURE 4B includes locking hubs 410 and 412, through which elongated piles are inserted and locked into place.
  • Locking hubs 410 and 412 are hollow round tubes with one side cut at an angle to match the interface of the pile and top plate (in other words, corresponding to the angle of the pile and the ellipse shaped openings in the plate).
  • the locking hubs 410 and 412 have a small threaded opening on at least one side to allow for the insertion of set screw 416. After one end of each pile is driven through the plate, the locking hubs 410 and 412 are slid onto the piles to the point where they contact the surface of the plate and the screws are tightened against the piles.
  • Locking hubs can also be held below the plate, for example locking hub 414, and the piles slid through so that it can be locked below the plate.
  • the locking hubs are larger than the elliptical holes on the top plate, and when tightened, restrict any movement of the piles relative to the plate, or the plate relative to the piles, creating a lock by fixing the angle of the piles relative to the elliptical holes, as the other locking components do, and/or by stopping any sliding of the piles - in one or two directions - relative to the plate.
  • the plates shown in FIGURE 4A are common mild steel, but may also be of spring steel, or a material with similar elastic properties, such that degrees of tightening can be developed, allowing for the presetting of a tension between the interconnected components and the upper ends of the embedded piles. Additionally, while the plates shown are flat, they may be curved, U-shaped, W- shaped, or other appropriate functional shapes.
  • FIGURE 5 is a series of perspective views of the locking components shown in FIGURE 4 and FIGURE 1, as well as additional variations of these components.
  • Locking component 510 is configured to work with the top plate shown in FIGURE 3 A.
  • Locking component 512 is configured to work with the top plate shown in FIGURE 2B.
  • Locking component 514 is configured to work with the top plate shown in FIGURE 2A.
  • the orientation of locking component 514 is perpendicular to locking component 102 to correspond to the orientation of the elliptical holes (and the piles into which they are driven) in the top plate in FIGURE 2A.
  • Locking component 518 is configured to work with a four pile configuration such as that shown in FIGURE 4 A, substituting for locking component 312.
  • Locking component 516 is identical to locking component 518, except that it also includes shaped indents configured to receive piles such that the piles are further secured along their sides when engaged with the locking component.
  • Other locking components may include these shaped indents as well, such as locking component 514.
  • FIGURE 6 is an alternative embodiment of the foundation system.
  • spring 600 and one or more removable spacers 602 are provided between the top plate 606 and the locking component 608 such that the spacers 602 keep the top plate 606 and locking component 608 at a predefined distance apart, causing the spring 600 to be expanded.
  • one or more spacers 602 are removed causing the spring 600 to compress, which in turn causes the distance between the top plate 606 and locking component 608 to be reduced until the piles 610 engage the locking component 608, and are locked into place in the elliptical openings on top plate 606.
  • the removable spacers 602 have angled tops and bottoms to facilitate spreading between the top plate 606 and locking component 608, and the removal of the spacers 602.
  • FIGURE 7 is another alternative embodiment of the foundation system.
  • block 700 includes driving cavity 712 to receive piles 702.
  • Block 700 may be comprised of concrete, wood, plastic, steel or any other appropriate material as would be recognized by one skilled in the art.
  • Block 700 is configured to be set in a conical shaped hole 710, such that a bottom portion of the hole will allow free movement of locking component 704.
  • Block 700 also includes bolt sleeve 706 to receive carriage bolt 708.
  • Bolt 708 is secured via nut 716.
  • Locking component 704 is held against the bolt head by retaining ring 720.
  • the retaining ring 720 may be omitted, and bolt 708 may be welded to locking component 704.
  • Cap 714 may be placed on piles 702 to prevent contaminants from entering the otherwise exposed open end of the piles 702.
  • This block embodiment may be a distributed load system with a pair of pins spaced apart every few feet, such as FIGURE 1 , or a concentrated load system with two or more pins and appropriate locking components, such as FIGURE 4A.
  • the bolt is slidable within the block, either through a sleeve or a cavity, allowing the bolt to pull up on the locking component 704, causing the locking component 704 to engage piles 702, thereby binding piles 702 in their driving cavities 712.
  • Bracket 718 can be used to attach a structure to the foundation system.
  • FIGURES 7B, 724, 7C, 726, and 7D, 728 are locking components that may be used with a four pin configuration.
  • Locking component 724 has a square hole 724 to keep the carriage bolt 708 from spinning when nut 716 is being tightened.
  • locking component 726 comprises half ellipses and locking component 728 comprises notch cuts.
  • the pyramid shape of locking components 722 and 728 are shorter and have a wider top than locking components 516 or 518, to ensure that the locking component 704 engages the piles 702 far enough below the base of the block 700 that a gap between the two is preserved that will allow for tightening and compression of the space and the binding of the piles 702 in their driving cavities 712.
  • the gap preserved between the base of the block 700 and locking component 704 is a minimum of 1 inch.
  • increasing the diameter or number of supportive piles increases their specific load resistance, as does increasing the size and strength of the locking components.
  • the embodiments can all be installed, when necessary for certain site conditions, such as heaving or expansive soils, so that the components do not rest on the soil, but are instead perched above it, supported by the driven piles.
  • All of the above embodiments allow adjustment, where the nuts or set screws can be loosened, or spacer blocks reinserted, and, to correct for some soil movement or unique loading event, the piles, and/or plates, and/or blocks (and structures attached) can be adjusted, leveled or reset. This feature also allows all piles to be fully removable, and/or replaceable.
  • the structure components and piles are raw, galvanized or painted steel, but may be of any appropriate material or alloy which possesses the necessary strength and characteristics required to remain competent and intact during installation, function in adequately transferring specific loads from the structure to the driven piles, and to sufficiently lock those driven piles under load.
  • Corrosive protection such as galvanizing may be substituted by any number of appropriate coatings or alternative protection methods, or may not be necessary, since in some instances, such as temporary installations or the use of certain alloys or the use of the components in certain specific environments, corrosion protective coatings may not be required.
  • bolts in all applicable embodiments are coated steel, but may be of differing materials and/or of differing fastening styles as appropriate.
  • the holes configured to receive the piles will have a shape corresponding to the piles they are configured to receive.
  • the rectangular holes in plates 902, 904, and 906, shown in FIGURE 9 are configured to receive a pile with a square cross-section, such as square 814 shown in FIGURE 8.
  • the perimeter of a hole configured to receive a pile will be larger than the perimeter of the corresponding pile, so that the pile can be locked at an angle (i.e., not perpendicular to the surface).
  • caps are made of rigid thermo-plastic. These caps may likewise be substituted by any number of similar materials, or may be eliminated depending on the site conditions, material and/or cross-section of the driven piles.
  • the angle of the piles range from 25 to 75 degrees depending upon the soil conditions and loading requirements, provided that driving hole plane to specific load path relationships are maintained, component to pile lock relationships are maintained, and/or ensuing surface structure relationships are maintained. In other embodiments, the angle of the piles may be less than 90 degrees or greater than 0 degrees. In preferred embodiments, the angle of two or more piles will be the same. As understood by one skilled in the art, piles may extend sufficiently above the top plate, as shown in FIGURE 10, to form a supporting frame for a surface structure above, such as a floor system or in the case depicted, a solar panel.
